A discussion of duality and analyticity

Summary  In this paper we first discuss how the Veneziano representation contains Regge poles. It does so in a very complicated way and even if the unitarization program were taken for granted extra problems would be expected. Second, the couplings of the elastic channel are studied as functions of the energy and of the angular momentuml. Appropriate average values of the angular momentuml seem to have a clear meaning and this is conserved also when the straight-line relationship amongl andm 2 of the model is broken. Although the general coupling case is not studied here the authors think that the dual model may have a more promising meaning if taken from this statistical point of view.
